Short answer: choose between the HK Audio LINEAR 9 110 XA and RCF KX 10-A for the deployment, not from the automatic ranking alone. Their driver format, power requirements, coverage, bass reach, output capability, and control features determine which is the more practical PA for a particular room or system.
The case for the HK Audio LINEAR 9 110 XA. High-quality vendor data returns a 6.34 ideal-subwoofer preference score with 75Hz measured extension, matching the LINEAR 7 110 XA’s result. MILAN networking and comprehensive remote DSP make it a strong systems-oriented choice for professional deployment.
The case for the RCF KX 10-A. The entry point into RCF’s flagship KX point-source range, with a 130dB claimed peak, a neodymium woofer and wide 100° x 50° coverage in a manageable 34.2 lbs (15.5 kg) cabinet.
Important trade-offs. Buyers who do not need networked audio may find better value in simpler mainstream 10-inch models, and its 129dB peak claim is unremarkable for the category. The local measurement is truncated and cannot produce a preference score, and pricing/retail availability are not yet well established for this model.
Buy the HK Audio LINEAR 9 110 XA when its stated format, coverage, and system features fit the job better.
Buy the RCF KX 10-A when its stated output, control, and deployment strengths better match the system.

Frequency Response Compared
Both speakers’ spinorama measurements, overlaid. A flatter line is more neutral: peaks sound forward or harsh, dips sound recessed. Each curve is shifted so its average from 300 Hz to 3 kHz sits at 0 dB, so loudness differences between the two are removed and only the shape is compared.
